Thanks, Joe. Looking first at our full-year results, as Joe just mentioned, ARLP again posted record annual financial and operating metrics in 2011, as EBITDA increased 14.3% to $570.8 million, and net income jumped 21.3% to $389.4 million or $8.13 per basic and diluted limited partner unit.
Operationally, the continued strong performance of our River View Mine and the return of our Dotiki Mine to full production early last year drove 2011 coal production up by 6.6% to 30.8 million tons. On the marketing front, ARLP continued to strengthen its long-term contract portfolio, captured increased pricing on export market sales and capitalized on coal broker job opportunities throughout the year. As a result, ARLP's average coal sales price increased $4.74 per ton sold and coal sales volume declined 5.4% to 31.9 million tons. These both combined to push 2011 revenues up by 14.5%, to over $1.8 billion. ARLP's record coal sales and production volumes, increased coal purchases and cost pressures all contributed to higher total operating cost. During 2011, costs were particularly impacted by difficult mining conditions at our Dotiki and Warrior mines throughout the year, development production activity at Tunnel Ridge and 3 longwall moves at our Mountain View mine.
In addition, increasingly stringent regulatory burdens resulted in increased costs and hurt productivity in all of ARLP's operating regions. Overall, during 2011, average price realizations per ton increased 9.3%, while operating cost per ton climbed 9.6%. Even though both of these increases were greater than we originally anticipated, ARLP's realized margin per ton in 2011 was in line with our expectations.
Turning now to results for the 2011 quarter compared to the 2010 quarter, higher coal sales volumes and prices combined to drive revenues up 13.4% to $474.6 million and contributed to a 5% increase in net income, which rose to $91.7 million. EBITDA for the 2011 quarter decreased slightly compared to the 2010 quarter to $129.2 million as higher operating costs and the pass through of losses related to our White Oak preferred equity investment weighed on ARLP's results.
Similar to my earlier comments on ARLP's full-year results, operating cost in the 2011 quarter were impacted by increased coal sales volumes and revenues, difficult mining conditions at Dotiki and Warrior, development production at Tunnel Ridge, and comparatively adverse geology at Mountain View immediately prior to its longwall move in December. Partially offsetting these increases, workers compensation expense declined sequentially by approximately $1.17 per ton. This reduction reflects the long-term benefits of ARLP's ongoing safety programs, which improved our accident and expense trends.
As mentioned, increasing regulatory burdens have been impacting us for some time, and they continue to significantly impact operating cost during the 2011 quarter. These results -- these impacts were felt most acutely at our Pontiki mine, which was idle for approximately 24 days as the mine worked with regulators to resolve a dispute affecting the single production unit. As a result of shutting down the entire mine, sequential production at Pontiki declined during the 2011 quarter by approximately 150,000 tons, and operating costs per ton increased approximately 27%. Unfortunately, this regulatory action will have a lasting impact at Pontiki, as the mine will operate with 3 mining units in the future, one unit less that was in production prior to the dispute.
Several other factors also impacted ARLP's results for the 2011 quarter. Due to our preferred equity investment at White Oak Resources, accounting rules require ARLP to reflect substantially all of White Oak's income and/or losses until such time as we achieve our preferred return. For the 2011 quarter, these pass through losses reduced ARLP's EBITDA and net income by approximately $4.3 million. During our analysis of the accounting for ARLP's investments in White Oak, we also determined that an adjustment to the rate used to calculate capitalized interest on our recent development projects was also required. As a result, interest expense in the 2011 quarter was reduced by approximately $11.2 million to reflect this nonrecurring correction of ARLP's capitalized interest calculations.
As we provide our initial look at 2012, we felt breaking down guidance between ARLP's ongoing operating activities and a separate impact of our White Oak investments would provide a clearer comparative reference to prior periods. So as we look first at ongoing operations, ARLP currently anticipates total capital expenditures in 2012 in a range of $400 million to $425 million. These include maintenance capital expenditures. As noted in our release, major capital projects this year include completion of longwall development at Tunnel Ridge and ongoing development activities at our new Gibson South mine. ARLP also has a number of significant maintenance projects scheduled for 2012, including transitions into new reserve areas at Dotiki, MC Mining in Mountain View, and completion of a new coal preparation plant currently under construction at our Dotiki mining complex.
We have consistently provided a view of maintenance capital over a 5-year horizon due to the inherently cyclical nature of these expenditures. For our long term distribution planning purposes, ARLP is currently estimating total average maintenance capital expenditures of approximately $5.50 per ton produced over the next 5 years. In light of the significant infrastructure projects planned for this year, however, actual operating necessity capital expenditures are expected to be approximately $7.50 per ton in 2012.
Coal production and sales volumes are expected to show strong increases in 2012 compared to 2011. These increases reflect 2 additional production units in the Illinois Basin, the loss of the production unit at Pontiki, typical fluctuations at various operations and, most significantly, the startup of longwall production at Tunnel Ridge. With this longwall now scheduled to start toward the end of the second quarter, we are updating estimated 2012 production from this new mine in a range of 3.1 to 3.4 million tons. Based upon our current operating plans, we now anticipate annual production capacity at Tunnel Ridge of 6.5 million to 6.8 million tons for 2013 and beyond. A run rate roughly 1 million tons per year higher than previous expectations.
Considering the pluses and minuses of these various factors, ARLP is currently estimating 2012 coal production in a range of 34 million to 35 million tons, and coal sales in a range of 34.75 million to 35.85 million tons. In addition to having approximately 97% of its anticipated 2012 coal volumes contractually committed and priced, ARLP has also secured coal sales commitments for approximately 33.5 million tons, 27.2 million tons and 19.8 million tons in 2013, '14 and '15 respectively. Of these amounts, approximately 7.7 million tons in 2013 and 7.1 million tons in both 2014 and '15 remain open to market pricing.
Based on sales commitments and estimates for our remaining open position, ARLP is expecting average coal sales price to increase by 2% to 4% in 2012 over 2011. Expectations of increased price realization and coal sales volumes are driving ARLP's estimated 2012 revenues higher to a range of $2 billion to $2.1 billion, excluding transportation revenues. ARLP's ongoing operating activities are also expected to generate 2012 EBITDA in a range of $590 million to $680 million, and net income in a range of $360 million to $440 million. It should also be noted that as a result of ARLP's ongoing capital investment projects and commencement of longwall production at Tunnel Ridge, DDNA [ph] is expected to increase by approximately $40 million to $50 million in 2012. This non-cash increase obviously has a meaningful effect on ARLP's estimated net income for 2012 compared to 2011.
Separate from the above guidance for our ongoing operations, ARLP's consolidated results in 2012 will also be impacted by our continuing investments in White Oak. We currently anticipate funding capital expenditures during 2012 of approximately $125 million to $150 million for reserve acquisitions and construction of surface facilities related to White Oak's Mine No. 1 development project, and an additional estimated $100 million to $125 million of preferred equity contributions.
As discussed above, the accounting rules require we record the pass through of losses related to our equity investments in White Oak, and as a result, we currently expect White Oak to negatively impact ARLP's 2012 consolidated EBITDA by $20 million to $25 million and net income by an estimated $15 million to $20 million. As previously disclosed, ARLP continues to anticipate its investments in White Oak will be meaningfully accretive to our financial results in the 2015 timeframe, once longwall production has begun at Mine No. 1.
Finally, ARLP entered 2012 with a strong balance sheet and significant available capacity. Our current revolving credit facility expires in the third quarter of this year, so we are planning to access the bank markets in the near term. As part of our planning, we will evaluate our options in the debt capital markets to ensure that ARLP has sufficient liquidity and flexibility to execute its plans.
This concludes our prepared comments. We appreciate your continued support and interest in both ARLP and AHGP. And now, with Jasmine's assistance, we'll open the call to your questions. Jasmine?
